Why Foundation Waterproofing Matters
- Robust Local Construction Activity. In the Tampa–St. Petersburg–Clearwater metro, about 1,158 new single-family home permits were issued in June 2025 (seasonally adjusted). [source]
- Code-Compliant But Risk-Prone Build Practice. Homes are built at existing soil grade, while Florida code requires the first floor to be at least 12 inches above finished grade. [source] [source]
- Delayed Degradation Leading to Moisture Intrusion. Around 8 to 12 years after installation, vapor barriers can deteriorate, allowing groundwater and rising water tables to penetrate the slab.
- Proactive Waterproofing Prevents Future Issues. In Clearwater’s environment, early waterproofing measures are key to long-term foundation health.
Expert Foundation Waterproofing for St. Petersburg’s Coastal & Storm Conditions
St. Petersburg’s low elevation, sandy soils, and shallow coastal water table make below-grade structures especially vulnerable to water intrusion. Many homes built across Pinellas County rely on thin vapor barriers that typically degrade after 8–12 years, letting groundwater and storm-driven rain rise into slabs and crawlspaces. Our team, led by water hydraulics engineer Jeff Earl, designs and installs engineered waterproofing systems that stand up to hydrostatic pressure, king tides, and hurricane-season rainfall.
Protecting Property Value & Closing Florida’s Code Gap
Florida has no dedicated below-grade waterproofing code. Local Pinellas County officials generally only require that the first living floor be at least 12 inches above finished grade, but this does nothing once a slab sits below the seasonal high water table. Our engineered solutions fill that gap, and every installation is backed by a Lifetime Transferable Warranty — critical for property value and required disclosure when selling a St. Pete home.
Foundation Waterproofing Company St. Petersburg
Jeff Earl is the MOST experienced Foundation Waterproofing Contractor in all of Florida!!!! In the State of Florida there are no waterproofing codes. If a below grade structure (new construction) is turned in for permitting than most building officials will refer to IBC (International Building Codes). Florida has elevation codes that site first floor elevation has to be a minimum 12″ above the finished exterior yard elevation. The reason for the building codes is simple. Florida has a high water table through out the state 80% is affected.

St. Petersburg Foundation Waterproofing FAQ
Does the Florida Building Code require below-grade waterproofing?
No. The Florida Building Code (FBC) doesn’t set specific waterproofing standards. In Pinellas County — where the water table can be just a few feet below grade and storm surges push it higher — a foundation must be built almost like “a boat” underground to resist hydrostatic pressure.
Do I need a building permit to waterproof a foundation in St. Petersburg?
No. Waterproofing, sump pumps, and exterior drainage systems do not require a permit in Florida. Only structural modifications — such as reinforcing or rebuilding foundation walls — would trigger permitting in Pinellas County.
How much does professional foundation waterproofing cost in St. Petersburg?
Most engineered waterproofing projects here run $20,000–$40,000, depending on water table depth, soil type, and property access. Acting before cracks and long-term movement develop helps avoid even higher structural repair costs.
Why is experience critical for waterproofing in St. Petersburg?
Because Florida has no waterproofing code and St. Pete sits on low, sandy, high-water-table ground, long-term success depends on field-proven engineering. An experienced contractor who understands Pinellas soils, tide-influenced water levels, and drainage failures can design a system that stays dry for decades.
